LIN'ING FOR TRANSMISSION .AND BRAKE BANDS.

Appneatpn mea may 1 1,`1925. serial No. 29,515.

To all whom t may concern.'

Be it known that I, CHARLES BRAHs, a citizen of the United States ofAmerica,

- and resident of Paterson, in the county of present invention is toprovide a woven or a textile fabric for use as a transmission or brakeband lining which is so'constructedv as to provide on the face whichcoacts with vthe transmission or brake drum means for preventing theglazing of the face whereby vto cause the same l'to hold and thusincrease the length of life and usefulness of the lining to a markeddegree.

The invention furthermore comprehends a .woven or textile fabric liningfor transmission or brake bands which is constructed in such la mannervas to provide pile threads extending through the thickness of thelining to constitute means for conveying 'oilto the active surface.

More specifically the invention comprehends in connection with amultiple interwoven ply fabric or textile lining for transmission andbrake bands, pile warp threads extending through the thickness thereofto provide means for precludingA the glazing of the active surface ofthe lining and further to provide means for conveying oil from the outerinactive surface to the inner active surface thereof.

The invention furthermore comprehends an improved woven or textilelining for the purpose specified which does not materially increase thecost of manufacture, which is 'comparatively' simple and which is highlyeiicient in itspurpose.

With the above recited and other objects in view. reference is had tothefollowing specification and drawingslin. \vvhich there is exhibited oneexample orembodiment ,of the invention which is in 11o-way intended as alimitation upon the scope or the appended claims as it is to be clearlyunderstood that variations and modifications.

which properly fall within the scope of said claims may be resorted towhen found expedient.

In the drawingssectional view through a woven or textile liningconstructed in accordance with the invention, parts being shown inbroken lines to illustrate the method of making the same. Fig. 2 is afragmentary plan view of the lining.

Fig. 3 is a of the lining.

Referring to the drawings by characters of reference -10 and 11designate the outermost warp threads and 12 the intermediate interwovenor interlocked Warp threads. 13 designates the weft threads with whichthe perspective view of a portion ligure l is a fragmentary longitudinalwarp threads 10, 1.1 and 12 are interwoven to produce a multipleinterwoven ply fabric orl textile. The present invention consists inWeaving a certain number of warp threads .14 to extendvrticallythroughout the thickness of the multiple ply fabric and cuttinoff the bight portions 15 illustrated in bro (en linesin Fig. 1,substantially flush or even with the active surface of the fabric sothat in eifect a plurality of pile warp lthreads 16 are provided on theactive face for the purpose of preventing glazing thereof in addition toconstituting Wicks for conveying through the thickness of the fabricfrom its opposite inactive face quantities of oil which are to be fed tothe active face. Under this arrangement the pile warps 16 which arepresented endwise to the trans- 'mission or brake drums constitute ineffect a nap which counteracts the glazing action on the active face ofthe body of the material.

The invention furthermore coinprehends aI method of producing a fabricof this class with pile warps extending through the thickness thereofwhich consists in alternately raising and lowering certain of the lthrough at an angle to the weave of the fabric. Y

2.*As a new article of manufacture, a lining for transmission bands,brake bands and the Vlike comprising a woven fabric body and pile warpthreads woven therethrough at a rightl angle to the weave of the fabric.

3. As a new article o f manufacture, a lining Vfor transmission bands,brake bands and the like comprising an interwoven multiple ply fabricbody and pile warp threads woven and extending through said body at aright .angle to the weave of thesaine.

4. Asa new article of manufacture, a lining for transmission bands,brake bands and the like comprising an interwoven multiple ply fabricbody and pile warp threads woven and extending through said body at aright angle to the weave of the same, the looped ends of said pile warpthreads on one face of the bodyi being cut of iiush therewith toconstitute means for preventing glazing of said face and serving aswicks for conveying oil through the body to the active face.

5. In a lining for transmission bands, brake bands and the like, aninterwoven multiple ply fabric body and threads extending therethroughai-,right angles to the weave and the like comprising ,a woven fabric* fbody and a plurality of substantially U-shaped pile warp threads havingthe legs thereof respectively woven and extending through the bodybetween the adjacent weft threads and between the warp threads thereofas and for the purpose specified.

8. vThe herein described method of producing woven fabric linings fortransmission bands, 'brake bands or the like consisting in weavingthrough the thickness thereof pile warp threads and cutting oifthelooped connecting portions of said pile warp threads flush withy oneof the facesof the lining body.

9. The herein described' method of producing woven fabric liningsfortransmission bands, brake bandsor the like consisting in alternatelyraising and lowering certain of the warp threadsy above and below theupper and lower faces of the body, maintaining the looped connectingportions of the pile warp -threads on one of the faces of the fabricabove said face and then cutting o said looped connecting portions iushvwith said face of the fabric.
